GEORGE FRANZ, OF CHICAGO, ILLINOIS.

GOLLAPSIBLE CHAIR.

Application filed February 17,- 1926. Serial No. 88,948.

This invention relates to certain novel improvements in collapsiblechairs and has for its principal object the provision of an improvedconstruction of this character which will be highly efiicient in use andeconomical in manufacture.

Among the salient objects of the invention is the production of anarticle of this character wherein the article can be expeditiouslycollapsed to provide a small compact parcel greatly facilitatingconveyance or storage thereof.

Astill further object of the.invention is the production of an articleof this character wherein there is provided a simple combination andarrangement of parts for collapsing the article by folding seat membersthereof upon each other whereby the supportinglegs of article are causedto simultaneously collapse upon folding of the seat members uponthemselves.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings illustrating the preferred form of construction, and in whic 1.I

Fig. 1 is a side elevational view of the invention illustrating thepreferred form of construction Fig. 2 is a top plan view of the same;

Fig. 3 is an elevation view of the invention illustrating the same incollapsed vention illustrating a modified form of con-.

struction;

Fig. 8 is an elevational view of the invention illustrating'a stillfurther modified form of construction; and

Fig. 9 is a fragmentary sectional detail view taken substantially online 9-9 of Fig. 8.

Referring again to-the drawings particularly to Figures 1 to 6inclusive, the article vention are indicated at 15 and these seat amembers when mounted in fiat horizontal position 'have adjacent edges 16in abutting relation with respect to each other: Formed in theseabutting edges are recesses 17 providing a slot 18 for the reception ofthe reduced portion 14. The seat members are pivotally connected to thisreduced portion for pivotal movement in a direction to dispose the seatsmember in substantially parallel relation with respect to each as bestillustrated in Fig. 3, whenthe article is in collapsed condition. Thispivotal connection is accomplished through the means of pintles 19having rivet heads 19' formed thereon to prevent self displacementthereof.

Mounted for slidable movement longitudinally of the body 10 is aconnecting collar 20. This collar is guided for movement in saiddirection through the medium of a guide bolt 21 working in the slots 11.

These slots 11 communicate with a longitudinally extending recess inwhich there projects an end portion 22 of an operating link 23 havingone end connected for operation with the guiding bolt 21 and an oppositeend operatively connected to a connecting block 24.

The collar 20 includes separable parts 20.

Pivotally connected to the parts of the collar between ears 25 thereofare link members 26 having outer end portions pivotally connected to theseat members 15 adjacent the ends thereof. This pivotal connected isaccomplished through the medium ofpin members 27 carried by brackets 28having portions 29 confined in recesses 29' formed in the seat members.

Connected to the lower end portion of the body 10, for movementrelatively of each other are supporting legs 30. This connec tiOn isaccomplished through the medium of hinge members 31. The lower endportions of the legs 30 are pivotally connected to the connectin block24 through the medium of links 32 aving inner end portions con nected topins 33 carried by the block 24 and having their opposite ends connectedto the legs 30 by means of screw staples 33.

As illustrated in Fig. 2 the seat members 15 are slotted as at 3a toprovide hand hold portions 35 facilitating collapsing the chair in thefollowing manner:

To collapse the chair the hand hold positions 35 are firmly grasped bythe hands at which time the seat members are pivoted toward each otherto move the collar 20 along the body 10 through the medium of the linkmembers 26, movement of the collar being guided by the guide bolt 21. Asthis collar moves in a direction toward the top of the body movement ofthe supporting legs is urged toward each other through the me dium ofthe operating link 23 and links 32.

As is evident from the drawings, when the seat members are disposed inclose parallel relation with respect to each other, the supporting legswill be fully collapsed extending substantially in alignment withrespect to the body 10. In position of the seat members and supportinglegs it is apparent to those skilled in the art that the chair can becollapsed to a small compact condition for purposes herein set forth asone of the obj ects of the invention.

It is also evident from the description herein that by relieving thesupporting legs of the weight of the chair that the legs will easilycollapse by folding the seat members upon themselves and that thefolding action of the seat members will cause the support ing legs tocollapse.

'When the chair is in extended position it will be noted that shoulders36 provided by the reduced portion 14 of the heart of the body willsupport the seat members when disposed in horizontal alignment.

In describing the modified forms illustrated in Figs. 7 to 9 it ispointed out that parts similar to the parts herein described will beindicated by similar reference char acters.

In Fig. 7 the seat members are operatively connected to supporting feet37 through the medium of link members 38 and 39 having end portions 38and 39 respectively operatively connected to operating arms 40 pivotallyconnected to the body 10 as at 41. In this form of construction thesupporting feet are pivotally connected to a reduced head 42 of the body10., This reduced head is confined in a slot 43 similar to the slot 18.These supporting feet are adapted to be disposed in close parallelrelation and substantial alignment with the body 10 when caused to pivotto such position upon folding of the seat members upon themselves insubstantial alignment with the body 10.

In Figures 8 and 9 the seat members 15 are pivotally connected toconnecting pins 4% working in slot 45 formed in guide plates 46 carriedby the body 10. In this form of construction the chair is supported inextended position by driving the tapered end 4:? of the body 10 into theground. A flange 48 is carried by the body to limit the length of thetapered end to be driven into the ground and to assist in preventingtilting of the body when in use.

The seat members of this construction are likewise folded uponthemselves when collapsed.

From the description herein it is apparent that the article can he usedas a table as well as a chair when in extended position.

While I have illustrated the preferred form of construction it isapparent that slight changes and alterations may be made duringmanufacture without departing from the spirit of the invention or thescope of the appended claim.

Having described my invention what I claim as new and useful is:

An article of the class described including a supporting member. seatmembers. means pivotally connecting the seat members to the supportingmember at one end thereof, supporting legs. means hingedly connectingthe supporting legs to the supporting member at the other end thereof,link members. means connecting the corresponding end portions of thelink members to the legs together. means pivotally connecting theopposite corresponding end portions of the link members together, otherlink members, means pivotally connecting corresponding end portions ofthe last mentioned link members to the seat members, acollar providing asliding connection between the opposite end portions of the lastmentioned link members and the supporting member, and an operativeconnection between the collar and the means connecting the said oppositecorresponding end portions of the first mentioned link members together.

In witness whereof, I have hereunto subscribed my name this 30th day ofJanuary A. D., 1926.

GEORGE FRANZ.
